Time Waveform Replication (TWR) for shock testing on shaker systems has been receiving some attention in MIL-STD-810G and elsewhere. The goal is to test components to measured field time histories for realism.
The concern was the water impact shock of the Shuttle Solid Rocket Booster (SRB). A large IEA avionics box was mounted in the fore and aft of each booster. Each IEA was recovered and flown on a future mission.
So there was a need to perform a shaker table shock test on the IEA using realistic time histories from measured impact data, to verify that the IEA could survive this event

Here is the software for the method in C/C++ : TWR.zip
I will include equivalent versions in Matlab, Python, Fortran and Perl in a future update revision.
